cryptlib is a security toolkit library that allows programmers to incorporate

s. Extensive documentation in the form of a 400+ page programming manual is available. At the highest level, cryptlib provides implementations of complete security services such as S/MIME and PGP/ OpenPGP secure enveloping, SSL/TLS and SSH secure sessions, CA services such as CMP, SCEP, RTCS, OCSP, and other security operations such as secure timestamping. Since cryptlib uses industry-standard X.509, S/MIME, PGP/OpenPGP, and SSH/SSL/TLS data formats, the resulting encrypted or signed data can be easily transported to other systems and processed there, and cryptlib itself runs on many operating systems—all Windows versions and most

It also implements a full range of certification authority (CA) functions provides complete CMP, SCEP, RTCS, and OCSP server implementations to handle online certificate enrolment/issue/revocation and certificate status checking. Alongside the certificate handling, it provides a sophisticated key storage interface that allows the use of a wide range of key database types ranging from PKCS #11 devices, PKCS #15 key files, and PGP/OpenPGP key rings to commercial-grade RDBMS and

It can be used with a variety of cryptography devices that have received FIPS 140 or ITSEC/Common Criteria certification. The cryptographic device interface also provides a general-purpose plug-in capability for adding new functionality that can be used by cryptlib. cryptlib is written in C and supports BeOS, DOS,
